Apache Kafka is an event streaming platform. It is a very high performing platform. It is an open-source platform available for everyone's use. Apache Kafka offers data pipelines to its users for secure transactions of data. Through Apache Kafka, users can stream their analytics and mission-critical applications. It is an amazing platform for data integration. Apache Kafka's excellent Connect interface allows its users to integrate with numerous event sources and event sinks, including but not limited to JMS, AWS S3, Elasticsearch and Postgres. Due to this, Apache Kafka has many users in several sectors of the market. It is being used by insurance, manufacturing, information technology (IT) and services, telecommunication, retail, banks and finance, insurance, energy, and utilities. Apache Kafka prides itself for zero message loss. It provides its users with online resources such as rich documentation, training, guided tutorials, sample projects, Stack Overflow and many more. It was designed to provide a high throughput, unified, and low latency platform for real-time data transactions. Apache Kafka groups random streams of messages together to form a large network packet. This large group has large sequential disk operations and contiguous memory blocks to convert random writes into linear writes.

Apache Kafka was first released in January 2011. It was originally developed by LinkedIn. It is written in Java and Scala. The latest version of Apache Kafka, i.e., Apache Kafka 2.8.0, released on 19th April 2021, has several improvements from the past release. Apache Kafka is used in cross-platform operating systems. It is characterized as a message broker and a stream processing platform.

Apache Kafka, like most platforms, does not run on a single server. It is operated on a cluster of servers that store and receive data as and when intended. Apache Kafka has a special filing system for the incoming data. The data received is divided into partitions and the partitions further into topics. Each data is saved with a timestamp. Apache Kafka has two main types of topics, viz. regular and compacted. The data saved under regular topics come with an expiry date. At the same time, the data under the compacted topic is saved forever. To carry out all the functions smoothly, Apache Kafka depends on five major APIs. These are Producer API, Consumer API, Connector API, Streams API and Admin API.
